NUMON N. HORTON, OF KANSAS CITY, MISSOURI.

HEATING, COOLING, AND VENTlLATlNG APPARATUS.

SPECIFICATION forming part of Letters Patent No. 245,380, dated August9, 1881.

Application filed February 15, 1881.

. To all whom it may concern Be it known that I, NUMoN N. HORTON, doctorof medicine, a citizen of the United States, residing at Kansas City, inthe county of Jackson and State of Missouri, have invented Improvementsin Heating, Cooling,

and Ventilating Apparatus, of which the following is a specification.

My invention relates particularly to certain improvements for theadaptation to the ventilation and heating and cooling of railwaycars ofa system of ventilation and heating or cooling which I have described inanother application.

My present improvements relate, first, to a mode of connecting my systemof heating or cooling and ventilating pipes with a locomoa tive-engineboiler for the purpose of applying the invention to railway-cars;second, to an improved arrangement of devices for delivering the heatedair and discharging vitiated air; and, third, to a coupling for the hoseby which the air is conducted from car to car.

In order that the invention may be fully understood, I will proceed todescribe it with reference to the accompanying drawings.

Figure l is a vertical longitudinal section of a baggage-car with myheating and ventilating apparatus applied. Fig. 2 is a longitudinalsection of the heating or cooling coil and its accessories on a largerscale. Fig. 3 is a vertical longitudinal section of a passengercar,showing the induction and discharge apparatus therein. Fig. 4 is alongitudinal section of a part of the air-pipe, showing the dampertherein and the mode of locking the same. Fig. 5 is a vertical sectionof the exhaust or discharge pipe and the nozzle therein on a largerscale. Fig. 6 is a perspective view of parts of the hose-couplingdetached. Fig. 7 is a side elevation of one of the couplingheads. Fig. 8is a longitudinal section of the two heads connected.

In Fig. 1 I have shown within the baggagecar, at B, a boiler, an d at Ean engine for working the fan F for producing a forced current of airafter the manner described in my other application, hereinbeforereferred to, for a system of heating and ventilating applicable tobuildings as well as to railway-cars.

A represents a drum or casing containing (No model.)

the heating or cooling coil C, which, for heatv ing purposes, issupplied with steam either directly from the boiler B or from theexhaust of the engine, as shown; or it may, in the application of myinvention to car-heating, be connected by a pipe, 0, with thelocomotive-boiler through a suitable hose and coupling, and byconnecting the said steam-pipe with the engine E, as shown, the boiler Bin the baggagecar may be entirely dispensed with.

The steam-coil C may either deliver the steam into the air through apipe, 0, asshown, or the circulation of steam therein may be soregulated as to return the entire Water of condensation into the boilerthrough a suitable pipe.-

F represents a fan, which is driven by the engine E by means of boltsand pulleys or other equivalent appliances, and is employed for forcingair through the pipe G and branches G G the first passing into thecasing or drum A, and the second around the same.

For cooling the air in hot weather cold water, either iced or not, ispassed through the coil C. i I

Both the drum A and the lateral passage G are connected to a commonconducting'tube or trunk, G by which the air, either heated or not, asdesired, is conducted and delivered to hose H H, connected by thecoupling I, so as to be passed from car to car throughout the entirelength of the train. V represents a two-way valve controlling thebifurcated or branched passages from the air-pipe Gr to the drum A andthe lateral pipe or passage G so that the entire body of air maybepassed through the drum A in contact with the heating or cooling coil Cor through the lateral passage Gr around the drum, so as to avoid beingheated or cooled, or any relative proportions of the air being passedthrough therespectivechannels. Theentirebodyofair delivered or conductedthrough the pipe or trunk Gr may be heated or cooled to the requireddegree.

The degreeot' heat is nicely regulated by the graduation oftherespective passages by means of the valve, as aforesaid, the hingedrod J, by which the valve is moved, being notched, as shown, and pressedforward by a spring, K, fixed to the outside of the pipe. The particularnotch in which the rod is held indicates the precise position of thevalve with respect to the passages which it controls. Theventilating-trunks L, within the passenger-cars,

take the air from the hose H at one end and deliver it to a similarhose, H, at the other end of the car, each hose being\provided with asimilar coupling, I, adapted for interchangeable connection, so that thecars may be connected in customary manner either end to, or either endof any passenger-car may be connected with the hose H of the baggage-carin which the air forcing and heating apparatus is contained.

To adapt the couplings to come together interchan geably, they are eachmade with a semicircular flange, p, to slip within the opposite head,asillustrated in Fig. 8, and each head has on one side a springcatch, q,and on the other a hole, a, to receive the spring-catch of the otherhead. \Vith the air-trunks L, within the cars, are connected verticalair-pipes M, leading down the sides of the car, between the windowsadjacent to the seats, and delivering air under control of registers N,which are accessible to the passengers.

In order to carry off vitiated air from the cars and facilitatethedelivery of fresh air within the same, either heated or not, as thetemperature of the atmosphere may require, 1 cmploy discharge-pipes 0,opening near the floor of the car, so as to take the coolerand morevitiated stratum of air, and having within them upturned nozzles P,connected by small pipes Q with the air-forcing pipes or trunks L, so asto cause an active induced current of air. The

discharge-pipes O are located, two in a car, at opposite diagonalcorners, in the places commonly occupied by heating-stoves.

It is manifestly unimportant whether the air-forcing fan F be located,as already described, so as to drive the air through drum A or lateralpipe G or both, or whetherit be located within the trunk G with whichthe said drum A and pipe Gr both communicate, so as to cause anexhaust-current through said drum A or lateral pipe G or both. I haveaccordingly shown at F a fan which will act by exhaust, as aforesaid;but it will be clearly understood that the force-fan F and theexhaustfan F will not both be required, but either may be used, aspreferred.

It is also manifest that any suitable form of rotary or reciprocatingblower or air-pum p may be used in lieu of common centrifugal fansindicated.

A damper is shown at T, in the air-trunk L at each end of the car, forthe purpose of clos ling said trunk at the rear end of a train.- Theshaft of said damper is provided with a crossbar or handle, U, forturning it, and with a square head, W, for the engagement of a pivotedforked catch, X, so as to hold the damper securely in either open orclosed position.

Having thus described my invention, the following is what I claim as newtherein and desire to secure by Letters Patent:

1. The combination, in a railway-car, of a suitable air-forcingappliance, F, an engine, E, for working the same, branched pipes GG G Gheater or cooler A O, and a pipe, 0, for supplying steam from thelocomotive to the engine E and heatingcoil O, as explained.

2. The combination, in arailway-car, of hotair trunks or conductors L,delivery-pipes M, and forced-exhaust apparatus consisting of thedischarge-pipe 0, opening near the floor, and the upturned nozzle 1contained therein, substantially as and for the purpose set forth.
